Someone smarter than me once said, “AI won’t replace you, but a person using AI better than you might.” I believe this is exactly right. Right now, we all need to be building the skills that help us become that person using AI better. Lucky for us, Amir Klein is already that person and has written a guide for the rest of us. Though it’s targeted at product managers, the advice and workflows can be implemented by anyone in any function. Thank you, Amir, for giving us a glimpse into the future and the concrete steps to get there.

The first month in my new role at monday.com, I was tasked with building our first AI agent. The goal was to create an AI co-pilot, something users could turn to for insights, explanations, or building complex workflows they wouldn’t know how to create on their own. To build that, I needed a ton of context—all the internal knowledge, decisions, assumptions, and scattered inputs that shape any product direction. And gathering all of that felt completely overwhelming.

I was drowning.

All that context lives everywhere: Slack channels, Notion pages, Monday boards, decks, Google Docs. Hundreds of tiny fragments I could never quite piece together. I kept running into mental blocks, forgetting what I knew from where, and getting stuck. Instead of trying to keep all of that context in my head like I always had, this time I wanted to try something new. I dumped everything I had into a ChatGPT Project, word-vomited all that was on my mind, and asked if it could help me get started. And boy, did it.

Finally, I felt like I could smell a roadmap on the horizon, a direction was forming, and things began to click. Even better, I felt somewhat in control without being stressed about storing everything in my head. I could store it in the AI instead—a second brain. Instead of all that information overloading my own brain and pulling my attention in a hundred different directions, I could finally focus on the product work I love and need to get right to be successful: understanding the problem, shaping the vision, and building something meaningful.

My good friend Tal taught us how to think with AI. I’m building on Tal’s post by showing what happens when AI becomes an extension of your mind—when it carries your context, grows alongside you, and ultimately amplifies what you’re capable of as a PM.
